Question

find the principal SI = ₹ 401.50 , Rate = 11% p.a. , Time = 5/2​

Answer 1

GIVEN,

S.I = ₹ 401.50

R = 11% per annum

Time = 5/2 yrs = 2.5 yrs

TO FIND,

Principle = ?

SOLUTION:

$S.I = \frac{PRT}{100} \\401.50 = \frac{P*11*2.5}{100} \\401.50 = \frac{P*27.5}{100} \\\frac{401.50*100}{27.5} = P\\\frac{40150}{27.5} = P\\1460 = P$

FINAL ANSWER:

Principle = ₹1460
